Traditional Chinese medicine composition, and preparation and application thereof

Embodiments of the present invention provide an oil-gas reservoir exploration method and apparatus and belong to the technical field of oil-gas exploration. The method includes: acquiring hydrocarbon source rock distribution, reservoir distribution, fault distribution and oil-gas reservoir distribution; determining at least one oil-gas accumulation chain according to the hydrocarbon source rock distribution, the reservoir distribution, the fault distribution and the oil-gas reservoir distribution; and determining exploration targets and an exploration order of oil-gas reservoirs according to the at least one oil-gas accumulation chain and the oil-gas reservoirs on the oil-gas accumulation chain. By using the oil-gas reservoir exploration method and apparatus, the exploration targets and the exploration order may be precisely and rapidly determined.

Oil-gas reservoir exploration method and apparatus

The present invention relates to a preparation method for a traditional Chinese medicine drop pill and a traditional Chinese medicine micro drop pill prepared by using the method, and in particular, the present invention relates to a micro drop pill preparation method with high drug-loading capacity, simple preparation process and high production rate and a micro drop pill prepared by using the method. Specially, The drop pill preparation method used comprises the following steps: (1) material melting step: heat melting a medicine and a drop pill matrix to obtain a molten medicine liquid; (2) dropping step: delivering the molten medicine liquid to a dripper, and acquiring medicine drops of the molten medicine liquid by means of vibration dropping; and, (3) condensation step: cooling the medicine drops with a cooling gas to obtain micro drop pills.

Formulation of a micro drop pill and the preparation method thereof

The present disclosure provide a method and device for optimal selection of fracturing stage clusters of continental shale oil horizontal well. The method includes: acquiring data information of a horizontal well to be fractured and data information of a key cored well; constructing a fracturing cluster evaluation index for the horizontal well according to the data information of the horizontal well to be fractured and the data information of the key cored well; and determining distribution of fracturing clusters and perforated interval clusters using the fracturing cluster evaluation index in conjunction with a principle of differential construction of horizontal well clusters. With the method and the device provided by the embodiment of the present disclosure, the problems of waste of resources and poor effect of oil production by fracturing, caused by uniform or overly dense distribution of clusters are solved.
