Firstly, polyacrylamide with 26 million molecular weight was compounded in lab through establishing optimum compounding initiator proportionality of 1:1. 3 and mass concentration of 170 mgL^(-1), temperature of 10 ℃, acrylamide mass percentage of 25%, electrical conductivity of 3.6 μSm^(-1) and pH value of 6.57. The salt-resistance, thermal endurance and shear-resistance of polyacrylamide could be enhanced b introducing sulfonic acid group or styrene sulfonate group or drawing the two groups above at the same time. Secondly, chelator HEDP, bactericide isoquinoline ketone and oxygen scavenger thiourea were optimized to improve the compatibility of polyacrylamide and formation water.

The dissertation mainly consists of two parts:1. The Reaction Chemistry of Alkynes under Palladium Catalysis Part 1 studies the reaction α,β-unsaturated carbonyl compounds with alkenylpalladium intermediate generated by nucleopalladation, and discovered 1 the Pd-catalyzed tandem addition reaction of halides, alkynes and α,β-unsaturated carbonyls,2 the four-component tandem addition reaction of halides, alkynes and α,β-unsaturated carbonyls, 3 the tandem intramolecular oxypalladation-conjugate additionreaction of alkynoic acids with α,β-enals. These new reactions provide notonly efficient highly stereoselective methods for the synthesis of γ,δ-unsaturated,polyunsaturated carbonyl compounds and γ-lactonic aldehydes, but also thebasic transformations for a number of C-C bond formation reactions which can be usedto design synthesis of many acyclic, cyclic or polycyclic compounds.
