Description
Technical field
The present invention relates to the both sexes potassium base polymeric alcohol water-based drilling that shale is crept into a kind of shale gas exploitation drilling process
Liquid, is particularly suitable for the drilling of the long net horizontal section of shale of microcrack development.
Background technology
Shale gas well generally uses oil base drilling fluid both at home and abroad at present, because oil base drilling fluid can improve hygroscopicity shale
Capillary pressure, prevents intrusion of the drilling fluid to shale, can be effectively by using oil base drilling fluid and synthetic base drilling fluid
The problem of solving hole instability.It is external using oil base drilling fluid system in terms of shale gas horizontal well wellbore stability is tackled
Current maximally effective measure.Even if using oil base drilling fluid, the shale formation of fracture or stratification development, it is necessary to reinforcing envelope
It is stifled, enter the pressure transmission (block fluid passage) that stratum is caused to reduce liquid.Oil base drilling fluid is in lubrication, anti-sticking and drop resistance
There is the incomparable advantage of water-base drilling fluid in terms of effect, can avoid dragging pressure problem during slide drilling, this is also that its is wide
Where the basic reason of general application.But because oil base working solution makes the wettability modification of low permeability pay and gas-bearing formation and causes wound
Evil, is greatly lowered reservoir permeability, so as to reduce oil well output.Indoor core experiment shows, when core is changed into by hydrophilic
During oleophylic, its recovery ratio drops to 17% by 51%.Therefore, it should cautiously be bored in low permeability pay using oil base drilling fluid and open production
Layer, when especially having emulsifying agent, surfactant in oil base drilling fluid.
Advantage and disadvantage water-base drilling fluid advantage compared to oil base drilling fluid has：1. it is environmentally friendly；2. natural gas leaching is easy finds；3. temperature
It is smaller to rheology impact；4. cost is relatively low；5. meet leakage to be easily processed, shortcoming has：1. borehole wall stability is poor；2. heat is steady
It is qualitative relatively poor, it is easy to high temperature gel；3. resistance tocrocking poor (solid phase and CO2、H2S gaseous contaminations), safeguard processing workload
Greatly；4. anti-sticking scarce capacity is lubricated.Therefore, develop a kind of novel water-based drilling fluid that can be suitably used for shale formation and substitute oil base brill
The problems such as well liquid can solve the problem that wellbore stability, reservoir pollution is then the key technology of current shale gas drilling well, is also domestic and international page
Where the difficult point of rock drilling well.
The content of the invention
The purpose of the present invention is：Borehole well instability problem when creeping into shale formation using water-base drilling fluid to overcome, suppresses
Shale formation aquation is caved in, effectively the closure micro-nano slit of shale, and a kind of both sexes potassium base polymerization for creeping into shale is provided for this spy
Alcohol water-base drilling fluid.
In order to achieve the above object, the present invention uses following technical scheme：A kind of both sexes potassium base polymeric alcohol of drilling well shale
