Abstract
The invention provides a slurry used for easily collapsed layer drilling in oil drilling and production, and belongs to the field of oil drilling engineering. The slurry is used for solving problems that in oil drilling process, well wall collapse is caused by easily collapsed layers, drilling speed and benefit are influenced seriously, and oilfield exploration and development progress is influenced. The slurry is prepared from, by weight, 15 to 30 parts of bentonite, 0.03 to 0.05 part of potassium polyacrylate, 0.1 to 0.2 part of drilling fluid flow pattern regulator 80A51, 3 to 5 parts of walchowite, 1 to 3 parts of sulfonated lignite, 0.2 to 0.5 part of hydroxyethyl cellulose, 0.2 to 0.5 part of glyceryl polyether, 0.6 to 1 part of basic zinc carbonate, 0.6 to 1 part of sulfonated tall oil, 0.1 to 3 parts of barium sulfate, and 1000 parts of water. The slurry possesses excellent leakproof wall-protection effects on easily collapsed layer drilling with high pressure coefficient, and is capable of increasing penetration rate appropriately on condition of collapse prevention.
Description
Technical field
The invention belongs to oil drilling engineering field, be specifically related to the mud crept into for the layer that easily collapses in a kind of petroleum drilling and mining.
Background technology
?
geological workin, utilize
drilling rigsthe column circular hole that the diameter be drilled to underground is less, the degree of depth is larger, also known as boring.Drilling well diameter and depth size, depend on drilling well purposes and mineral products depth of burial etc.Drill for oil,
sweet natural gasand
underground waterdrilling well diameter all larger.Main function is: 1. obtain underground geological material, namely take from drilling well rock core, the ore deposit heart,
landwaste, liquid sample,
gaseous statesample etc.2. conduct
geophysical well loggingpassage, obtains rock ore bed various
geophysical fielddata.3. observe as artificial channel
underground waterthe hydrogeological current intelligence of layer.4. be used as visit, adopt combination, tap ground water resources, oil gas,
underground heatdeng drilling well.
Drilling well is divided into by purposes usually
reconnaissance geological surveyor prospect drilling, hydrogeology drilling, well or engineering geology drilling well,
geothermal drilling, petroleum drilling, coal driling,
ore fielddrilling well, building ground drilling well etc.
In CONTROL OF DRILLING PROCEDURE, often can encounter the layer that easily collapses, cause slump in, have a strong impact on drilling well working speed and benefit, hinder the progress of this In Oil Field Exploration And Development work.
Summary of the invention
For solving the problem, the invention provides the mud crept into for the layer that easily collapses in a kind of petroleum drilling and mining, adopting following technical scheme:
For the mud that the layer that easily collapses creeps into, it is characterized in that, by weight, its formula is: wilkinite 15 ~ 30 parts; Polyacrylic acid potassium 0.03 ~ 0.05 part; Flow pattern regulator 80A510.1 ~ 0.2 part; Valchovite 3 ~ 5 parts; Sulfonated lignite 1 ~ 3 part; Natvosol 0.2 ~ 0.5 part; Glycerin polyether 0.2 ~ 0.5 part; Zinc subcarbonate 0.6 ~ 1 part; Sulfonation Yatall MA 0.6 ~ 1 part; 0.1 ~ 3 part, barium sulfate; 1000 parts, water.
Beneficial effect of the present invention is as follows:
1. the mud crept into for the layer that easily collapses provided by the invention, the layer that easily collapses for high pressure coefficient creeps into has outstanding leakproof retaining wall effect, and on anti-collapse basis, suitably can improve rate of penetration.
2. the mud crept into for the layer that easily collapses provided by the invention, the layer that easily collapses also be applicable under deep-well section high temperature, conditions of high density creeps into.
