a resin formed by reaction of polyhydric alcohols and polybasic salts. Saturated or unsaturated oils or fats are involved.

n: a compound derived from an alkane by removing one hydrogen atom.

n: A kind of anionic surface active agent. Mainly used as emulsifier of water base drilling fluid and improving temperature resistance capacity of drilling fluid in the deep well.

n: A kind of non-ionics, used as foaming agent and emulsifier of foam drilling fluid.

n: a process for manufacturing components for 100-octane gasoline. An alkyl group is introduced into an organic compound either with or without a catalyst. Now usually used to mean alkylation of isobutane with propene, butenes, or hexenes in d1e presence of concentrated sulphuric acid or anhydrous hydrofluoric acid.

a reverse cracking process that convents hydrocarbon light ends (olefins) into longer chain, liquid fuels.

n: Affiliated to a kind of parbighite that can combine with alkylene, usually used as diluent and calcium remover which can resist certain temperature.

n: A kind of polymer synthetised by oxirane and other organic compound.

n: The nipple whose whole length is lathed with thread.

n: in tank sampling, a sample that is obtained by submerging a stoppered beaker or bottle to a poinias near as possible to the draw-off level, then opening the sampler and raising it at a rate that makes it about three-quarters full (maxi- mum 85%) as it emerges from the liquid.

a pool in which the total oil or gas production is restricted and allocated to specific wells as defined in a proration agreement.
