Mud-sand separator for petroleum drilling

Abstract

The invention discloses a mud-sand separator for petroleum drilling. The mud-sand separator comprises a machine frame, a mud temporary storage pool, two mud outlet pipes parallel to each other, a feeding pipe and a plurality of cyclone desanders, wherein the machine frame comprises a base in the shape of a rectangular frame, four first stand columns, a fixing frame and four second stand columns; a vibration sieve and the first stand columns are fixed to the base; the top ends of the four first stand columns and the lower ends of the four second stand columns are fixed to the four corners of the fixing frame; the mud temporary storage pool is welded in the fixing frame; a sewage outlet is formed in the bottom of the mud temporary storage pool; the mud outlet pipes are welded at the top ends of the second stand columns; a row of branch pipes are arranged on pipe bodies; the feeding pipe is fixed to the second stand columns, parallel to the mud outlet pipes and positioned above the mud temporary storage pool and below the mud outlet pipes; the cyclone desanders are mounted in two rows on two sides of the feeding pipe; and the top of each cyclone desander is connected with each branch pipe, the upper part of the cyclone desander is connected with the feeding pipe, and a sand outlet is formed in the bottom of the cyclone desander. According to the mud-sand separator, the cyclone desanders are adopted for mud separation simultaneously, so that the processing efficiency is high; the mud temporary storage pool is additionally arranged, so that empty opening is avoided and the energy is saved; and the mud-sand separator has the advantages of low cost and convenience for carrying.

Description

technical field [0001] The invention relates to the technical field of petroleum machinery, in particular to a sediment separator for petroleum drilling. Background technique [0002] During the entire drilling production process, the main pollutants are waste mud and cuttings, natural gas returned with drilling fluid circulation, H2S gas, mixture of oil gas and drilling fluid, etc. These pollutants are discharged the most, and the energy consumption of treatment , The material consumption is the largest, and the impact on the environment is also the largest. In the process of well control operations, such as overflow, well kick shut-in and well killing, etc., in order to avoid out-of-control blowout and fire on the well site, as well as possible personnel, equipment, wellbore unsafety and environmental pollution caused by it, pressure must be Blowout. According to the requirements, an outlet of the choke and kill manifold must be connected with a 100m blowout pipeline to ...
