System for automatically and quickly distributing drilling liquid

Abstract

The invention discloses a system for automatically and quickly distributing drilling liquid. The system comprises a programmable logic controller (PLC) automatic control system, an air source system, a storage system, a dry mixing system and a slurry mixing system; the air source system comprises an air storage tank, a large-scale air compressor, a dry cooling machine, a small-scale air compressor and an air supply pipeline which are uniformly distributed on a forced draught fan package; the storage system comprises a raw material storage tank, an additive storage tank, a dust removal tank, weighing sensors which are arranged at bottoms of the raw material storage tank and the additive storage tank, a raw material gas conveying pipeline and a dust removal pipeline; the dry mixing system comprises a primary mixing tank and a batch mixing tank which are arranged on a dry mixing package, weighing sensors which are arranged at bottoms of the primary mixing tank and the batch mixing tank, a primary mixing pipeline, a batch mixing pipeline, and a primary mixing tank and batch mixing tank mixing circulation pipeline; and the slurry mixing system comprises a stirring pool, a stirrer which is arranged on the middle part of the stirring pool, a diffusion groove which is formed on one side of the stirrer, a high-energy mixer which is arranged on the upper part of the diffusion groove, a slurry mixing pipeline, a slurry conveying pipeline and a densitometer which is arranged on the slurry conveying pipeline; and all the systems are matched to realize automatic slurry distribution.

Description

technical field

[0001] The invention relates to a slurry mixing system used in drilling construction in mountains, forests and great rivers, in particular to an automatic rapid slurry mixing system for drilling fluid. Background technique

[0002] The Northeast Sichuan region is particularly rich in natural gas reserves. With the continuous development of oil and gas fields, oil and gas reserves and oil and gas production continue to decline, which can no longer meet the needs of the motherland's construction. There are abundant gas sources in China, but it is very difficult to develop natural gas in Northeast Sichuan, because the gas wells drilled are distributed in mountains and rivers, and there are no conventional roads, so the transportation is particularly difficult, and the drilling equipment and drilling slurry materials are transported after the construction of dirt roads , especially the mixing materials and slurry mixing, the drilling slurry mixing process on the ...
