Method and System for Forming a Non-Circular Borehole

System and methods for creating shaped, non-circular boreholes in rocks especially for use with geothermal heat pump applications and for increasing wellbore support in applications such as horizontal oil and gas drilling are described. The systems and methods when applied to geothermal heat pumps create an elliptical shaped hole that is optimized for placing heat transfer tubes with a minimum of grout used. The significantly reduced cross-sectional area of the elliptical borehole also increases the overall drilling rate in rock and especially in hard rocks. In horizontal hard-rock drilling, creation of a horizontal non-circular borehole or modification of a circular borehole to a non-circular geometry is used to stabilize the borehole prior to casing insertion, and may also allow the use of lower mud pressures improving drilling rates. The system uses a non-contacting drilling system which in one embodiment uses a supersonic flame jet drilling system with a movable nozzle that swings between pivot points. In a second embodiment the elliptical shaped hole is created by an abrasive fluid or particle bearing-fluid or air jet drill that moves between pivot points. In another embodiment a non-contacting drill can use dual parallel nutating nozzles that create a pair of overlapping circular holes. The non-circular shaped hole is created by either the high temperature flame or water-particle jet or chemically active fluid jet as it removes rock material by erosion, dissolution and or thermal spalling. Modifications of circular boreholes to a generally elliptical shape can also be done using milling or jetting techniques.

Wet coke-quenching aerial fog processing method and device based on non-thermal plasma injection

The invention discloses a method and a device for processing wet quenching coke gas fog on the basis of athermal plasma injection. The method comprises the following steps that: in the ascending process, the hot gas fog generated by wet quenching coke sequentially passes through three processing steps including spray cooling, pre-dedusting on a baffle plate and athermal plasma purification, and is cooled in a spray cooling area; the cooled gas fog enters a pre-dedusting area on the baffle plate where the thicker and bigger water particles and coke powder in the gas fog are separated from the gas fog and impact to the baffle plate under the action of inertia; the remaining gas fog continues to ascend and enter an athermal plasma purification area where organic components, ammonia nitrogen and cyanide in the gas fog are oxidized by the athermal plasma; the water particles and the coke powder are charged and are transferred to a trapping pole plate directionally under the action of a high voltage electric field; and then the gas flow after subjected to the athermal plasma purification area continuous to ascend to the top of a coke quenching tower to be discharged. After the processing steps, the contents of water vapor and the coke powder discharged outside after one ton of coke is produced are controlled to be less than 0.05 ton and 5 grams respectively, and the removal rate of the organic components, the ammonia nitrogen and the cyanide can reach more than 80 percent.

Novel and efficient electrostatic pre-coalescence method and device applied to dehydration and desalt of crude oil

The present invention discloses a novel and efficient electrostatic pre-coalescence method and a device applied to dehydration and desalt of crude oil. The invention is used for dehydration of crude oil in the system of oil-gas gathering and transportation in oil fields and for dehydration and desalination of oil refineries, therefore enables the small water particle dispersed phase in the crude oil emulsion to coalesce and grow. The core part of the device is an electrode assembly comprising an electrically conductive metal rod, multilayer cannular electrodes vertically and coaxially mounted, and tabular electrodes parallelly mounted. When high pressure alternating current is applied to the electrode assembly, the dispersed phase water particles in the crude oil emulsion undergo demulsification because of the mechanism of dielectrophoresis coalescence and vibration coalescence, thereby the dispersed phase water particles coalescing and growing up, the subsequent time of gravity settling being reduced notably and the process efficiency being improved. Moreover, the device is compact and efficient. On the basis of the mechanism of dielectrophoresis phenomenon, the dosage of chemical demulsifiers and the total operating cost can be reduced and the economical benefit of oil refineries can be improved.

Novel high-efficiency crude oil electric dehydration and desalination method and equipment

The invention discloses a novel high-efficiency crude oil electric dehydration and desalination method and novel high-efficiency crude oil electric dehydration and desalination equipment, which can be used for dehydrating and desalinating crude oil emulsion in oil refineries. The processing equipment mainly comprises an inlet component, a tank and an electrostatic precoalescer; when a high-voltage explosion-proof transformer outside the device applies high-voltage alternating current to the crude oil emulsion in a corrugated hollow tube through metal electrode plates by a high-voltage insulating wire, a non-uniform alternating current field is produced between the electrode plates to cause dielectrophoresis coalescence of dispersed phase water particles; the flow state of the crude oil emulsion in the hollow tube is turbulent flow, and the turbulent flow increases the collision probability of the dispersed phase water particles in the crude oil emulsion and obviously shortens hydraulic retention time; and a flowing passage in the electrostatic precoalescer can be designed to be corrugated circular or wavelike quasi-rectangular. By using the method and the equipment, the dispersed phase water particles subjected to electrostatic precoalescence can obviously reduce subsequent gravity settling time and improve the processing efficiency; and after the crude oil emulsion enters the tank from the inlet component at the left end, the crude oil emulsion flows along the horizontal direction and can reduce the power consumption of an inlet.
