Fine naming method of tight sandstone and determination method of mineral content of rock

Номер: CN116029078A
Принадлежит:

The invention relates to a fine naming method of tight sandstone and a rock mineral content determination method, and belongs to the technical field of rock mineral identification. The fine naming method comprises the following steps: acquiring Fe element content, Al element content and Si element content in a rock skeleton to be named in a target area, and calculating the contents of rock debris, feldspar and quartz by using an X element content-rock debris content model, an aluminum element content-feldspar content model and a silicon element content-quartz content model in the framework, then calculating the relative content of the rock debris, the relative content of the feldspar and the relative content of the quartz, and finely naming the rocks in the target area by using a sandstone triangular chart. According to the method, the rock can be finely named in real time on the petroleum drilling site, the defect that fine naming of the rock is discontinuous after the mineral content ...

Номер: CN116023584A
Принадлежит:

The invention relates to a polymer and a preparation method thereof, and a temporary plugging agent and a preparation method thereof, and belongs to the field of oilfield chemistry. The preparation method of the polymer disclosed by the invention comprises the following step: enabling dimethylaminoethyl methacrylate, cyclohexyl methacrylate, allyl propanesulfonic acid and bromododecane to react in the presence of a first initiator to obtain the polymer. The preparation method of the polymer is simple to operate, and when the prepared polymer is used for preparing the polymer temporary plugging agent, rigid groups are introduced into polymer chains, so that the mechanical damage resistance of the temporary plugging agent in the granulation process can be enhanced, molecular chains of the temporary plugging agent can be more easily entangled, the dissolution time of the temporary plugging agent can be controlled, and the stability of the temporary plugging agent is improved. In addition, ...
