Embodiment 1

[0012] Embodiment 1 Take by weighing acrylic fiber 100kg, water 600kg, catalyst potassium polyuretate 7kg polyacrylamide 0.7kg sodium carboxymethyl cellulose 21kg, drop in the reactor, the reactor is airtightly heated, when the reactor temperature reaches 200%, Stop heating, at this time the corresponding pressure should be 1.5Mpa, keep the temperature for 12 hours, and when all the raw materials in the reactor are hydrolyzed from the liquid body to the liquid body, reduce the temperature to 170, put the semi-finished product formed at ℃ into the liquid storage tank, and the liquid will After spray drying at about 160°C, the hydrolyzed polyacrylonitrile compound ammonium salt is formed.

Embodiment 2

[0013] Example 2 After spray drying in Example 1 to generate hydrolyzed polyacrylonitrile compound ammonium salt, add 25kg of Phoebe powder that has passed through a 20 mesh sieve. The specific preparation method of Example 3-6 is the same as that of Example 1 or Example 2, except for the components The weight proportions are different, but all have the effect indicated by the present invention.

Abstract

The invention discloses a petroleum drilling additive with polypropylene ammonium salt and a preparation method of the petroleum drilling additive. The petroleum drilling additive is characterized by comprising the following components in parts by weight: 100-200 parts of acrylic fibers, 600-800 parts of water, 7-12 parts of polyacrylate, 0.8-1.2 parts of polyacrylamide, 5-10 parts of a cross-linking agent and 50-60 parts of phoebe zhennan powder. By adopting the petroleum drilling additive, the filter loss and the apparent viscosity of mud can be further reduced, potential safety hazard caused by the situation that hydrolysis polyacrylonitrile ammonium salt can be produced under a relatively large pressure condition (about 2.1MPa) can be avoided, the amount of additives in the mud can be reduced, the potency ratio of a product is increased, and thus the drilling cost can be effectively lowered.

Description

technical field [0001] The invention relates to a petroleum drilling aid containing polypropylene ammonium salt and a manufacturing method thereof. Background technique [0002] In oil drilling operations, people in the industry often use bentonite and water to make drilling mud to facilitate the normal operation of drilling tools. In order to reduce the fluid loss of drilling mud and the apparent viscosity of drilling mud, it is usually added hydrolyzed polyacrylamide ammonium salt produced by the reaction of polyamide and water, which can significantly reduce the filtration of drilling mud as a drilling aid. Loss and apparent viscosity of the mud. However, there are still some shortcomings in using hydrolyzed polyacrylonitrile ammonium salt as a drilling aid. One is that the ice-decomposed polyacrylonitrile ammonium salt has relatively high pressure in the production process (usually the reaction pressure is controlled at (about 2.1Mpa), so the safety of its production i...
