Lai Shenghua,Liu Wenbi,Li Defa,et al.Characters of pelite-fracture reservoir and factors controlling fracture development.Minerals and Rocks,1998,18(2):47-51.
The product is widely used for protection and partition in such fields as grassland,meadow,woods,fowlery,husbandry,sportground,virescence land,riverbanks,bridges and reservoirs.
Using flow sediment laden formula set by Hanqiwei and overyear runoff,sediment data,the sediment retaining prediction of Manwan reservoir is carried out.
Nonsandstone reservoirs between salt beds of Qianjiang Formation in the Qianjiang Sag of the Jianghan Basin are mainly composed of dolomicrite,glauberite rock,mudstone and their peperite.
The karst depression belongs to the accumulative area of surface water and subdrainage area of subsurface water, the karstification is relatively week, and reservoirs are undeveloped.
Dissolution is controlled by both sedimentation and tectonization, and the converted degree on reservoirs is closely related to sedimentary facies and the distance from unconformity interfaces.
The minimum underbalance is independent of viscosity and compressibility and of reservoir fluids.It is a function of the formation porosity, permeability and radius of perforation channels.
It's a residual mountain(unaka) which were a set of thrust blocks under the erosion unconformity.It's reservoir pore space is a fracture-vug-pore system of Ordovician carbonate karst.
The drilling results and drill stem test result prove that the prediction results of seismic nonelastic effect completely coincide with the actual gas-bearing Situation in the reservoir.
